Fits: Boston 2-post lift – main lift nut PB1
The Boston Main Nut PB1 is an OEM-specification replacement nut for Boston 2-post lift – main lift nut PB1. The lead screw nut is one of the most safety-critical components on a 2-post vehicle lift. The main lift nut engages the rotating screw to raise and lower the vehicle; the safety nut acts as a secondary catch if the main nut wears or fails.
Worn or damaged lift nuts cause uneven lifting, excessive play in the screw, or in severe cases complete loss of load control. Regular inspection and timely replacement is essential for safe lift operation. All Lift Spares Direct lift nuts are manufactured to original equipment specification and carry a 12-month guarantee.
